Graphic driver support on BeagleTouch with QT

Varun Sodhi

Hi,

We need to enable Graphic driver support on BeagleBoard. We are using BeagleTouch kit (BeagleBoard C4 with 4.1" resistive LCD touchscreen) from Liquidware for our development.

We have compiled QT-embedded with SGX support but while running the application on the board we are getting the below error. 

Error: 

/dev/fb0: could not find a suitable PVR2D pixel format 

Could not initialize EGL display - are the drivers loaded? 

/dev/fb0: could not find a suitable PVR2D pixel format 

powervr: driver cannot connect 

Aborted

 
Below is the list of all the steps / things we have done to enable the graphic driver support.

1. Compiled QT-embedded, libgles-omap3 and omap3-sgx-modules using openembedded recipies. 

2. And configured QT with : 

-embedded arm -egl -plugin-gfx-transformed -plugin-gfx-qvfb -plugin-gfx-vnc \

-plugin-gfx-directfb -plugin-gfx-powervr -opengl es1 -openvg \ 

-plugin-mouse-tslib -qt-mouse-pc -qt-mouse-qvfb -qt-mouse-linuxinput 

-qt-mouse-tslib -qt-kbd-tty -qt-kbd-linuxinput -openssl \ 

-DQT_KEYPAD_NAVIGATION -D QT_QWS_CLIENTBLIT -D QT_NO_QWS_CURSOR 

Booted from minicom with following env.

OMAP3 beagleboard.org # setenv bootargs console=ttyS0,115200n8=noinitrd ip=dhcp rw root=/dev/mmcblk0p2 omapfb.mode=lcd:480x270MR-24@60 

OMAP3 beagleboard.org # boot 

After Booting lsmod shows: 

Module                  Size  Used by 

pvrsrvkm              124693  2 bufferclass_ti,omaplfb 

omaplfb                 8942  0 

bufferclass_ti          4768  0 



Command Used: 

root@beagleboard:~# qtdemo -qws -display powervr 


Error: 

/dev/fb0: could not find a suitable PVR2D pixel format 

Could not initialize EGL display - are the drivers loaded? 

/dev/fb0: could not find a suitable PVR2D pixel format 

powervr: driver cannot connect 

Aborted 

Dmesg Output: root@beagleboard:~# dmesg | grep PVR
PVRSRV_PIXEL_FORMAT_ARGB8888

Also, Please find attached, strace log and dmesg log for the same. 

We googled this error, and found this BeagleBoard's Google Groups link.

It says "use the sgx libs from the angstrom feeds, those fixup the pixelformat" 

But as mentioned before, we are using open. embedded recipes only, which we suppose are same as Angstrom's. 


Also , Step III at this Google Code link, suggests, to erase the nand and reboot after running this command :

# setenv mmcargs 'setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait omapfb.video_mode=1024x768MR-16@60'

# saveenv

After this also, the dmesg output and the error remains same as described above.

We have followed all the steps of this Nokia-QT Labs Blog.


Looking forward for some solution.

Thanks,

Varun Sodhi
